Human body-balancing footwear capable of preventing knock-knees and providing cushioning suitable for the weight of wearer

ABSTRACT

Disclosed is a footwear (including shoes, sneakers, and like, and hereinafter, referred to as “footwear”) which is produced on the basis of ergonomics, and which includes a heel part provided at a rear portion of a sole part, and an impact absorbing cap detachably coupled with the heel part. The footwear absorbs external impacts generated during walking as much as possible in three stages. The heel of the footwear is divided into a left section and a right section, and is replaceable at any time. The footwear prevents deformation in the ankle joint and knock-knees or bandy-legs caused by a difference in wear between the two heels of shoes.

TECHNICAL FIELD

The present invention relates to a footwear based on ergonomics. Moreparticularly, the present invention relates to an ergonomic footwearcapable of absorbing external impact generated when a person walks inthree stages, preventing the legs of adolescents under the growth periodfrom being knock-kneed or bandy-legged as the ankle-joint of theadolescent, which is gradually twisted due to the difference in the wornof the heel part of the footwear, exerts a bad influence on the legjoint of the adolescent, maintaining the body balance of all persons,and allowing the person to feel the most comfortable by providing acushion function suitable for the weight of the person.

BACKGROUND ART

In most soles of typical footwears, a heel part is completely separatedfrom a foresole part regardless of the types of the footwear such asathletic shoes and dress shoes. Accordingly, the weight shift of a useris not natural in walking, so that the user may walk with difficulty. Inaddition, the end portion of the heel part protrudes at a right angle,so that the protruding end portion may uselessly apply impact to a userfoot in many cases.

In addition, in the case of a footwear having a completely-flat sole tonaturally shift the weight of the user, even if a small object is pinnedunder the sole of the footwear, the footwear may be pressurized overall. A footwear with a sole having a convex pattern at the centralportion thereof is designed without taking into account the movement ofthe ankle joint. Accordingly, if a user does not significantly practicewalking in the footwear, the user may not walk comfortably. In addition,when the user keeps standing for a long time or mainly uses masstransportations, the user may not keep the balance of the body. In thiscase, the user must significantly make effort to keep the balance of thebody.

In addition, the cushions of all footwears are made of the same springor the same cushion material regardless of the weight of the user.Therefore, if a lighter user uses the footwear, the cushion feels hard,and if a heavier user uses the footwear, the cushion function is notsmoothly performed, so that the footwear may act only as a foot cover.

The cushion of the typical footwear is advantageous to average-weightedpersons in terms of impact absorbing. However, since the weight of theuser is not naturally moved, and one side of the heel part of thefootwear is not prevented from being worn early, an ankle joint of theuser may be deformed. In particular, the adolescents under the growthperiod are subject to the deformation in the ankle joint, so that thelegs of the adolescents may be knock-kneed or bandy-legged.

Further, the balance of the whole body of the user may be collapsed, sothat the health of the user may be destroyed. Nevertheless, the aboveproblems have not been solved yet.

DISCLOSURE Technical Problem

Accordingly, the present invention has been made keeping in mind theabove problems occurring in the prior art, and an object of the presentinvention is to provide a footwear, in which a heel part of the footwearis formed in the same shape as that of the heel of a user foot in thestate the an impact absorbing cap is seated on the footwear. The outsideof the heel part of the footwear is aligned in line with a foresole partof the footwear, so that the weight shift of a user can be obtainedsmoothly from the heel part to the foresole part along the arch shape ofthe user foot. A weight-adjustable cushion is provided so that the usercan feel comfortable regardless the weight of the user. Since the shapeof the sole part of the footwear is similar to the shape of the sole ofthe foot of a healthy person, even if a user walks in the footwear, theuser can feel comfortable as if the user walks in bare feet on acushiony place. The footwear has the outer portion, the height of whichis properly increased based on ergonomics, to align the ankle of theuser in line with leg bones of the user even if the user keeps standingor even if the user walks with the user feet apart, thereby contributingto the health of the whole body of modern people as well as the feet andankles of the modern people. In particular, the footwear can prevent asituation in which the ankle joint of adolescents under the growthperiod is affected by the deformation in the heel of conventionalfootwear so that the legs of the adolescents may be knock-kneed or bebandy-legged.

Technical Solution

In order to accomplish the objects, according to one aspect of thepresent invention, there is provided a human body-balancing footwear forpreventing knock-knees and bandy-legs. The human body-balancing footwearincludes a heel part provided at a rear portion of a sole part, and animpact absorbing cap detachably coupled with the heel part.

The impact absorbing cap includes a first cap coupled with an outer sideportion of the heel part corresponding to an outer portion of a foot ofa user and a second cap coupled with an inner side portion of the heelpart corresponding to an inner portion of the foot of the user. Thefirst and second caps are replaceable.

In addition, the impact absorbing cap includes a first cushion partcoupled with a bottom surface of the heel part, a second cushion partcoupled with a rear surface of the heel part, and a third cushion partlinking the first cushion part with the second cushion part in a roundform.

In this case, the human body-balancing footwear further includes alinking member linking the heel part with a front portion of the solepart along an edge of the heel part corresponding to an outer portion ofa foot of a user, so that the user safely walks by allowing a tibia ofthe user to maintain balance of the user when the user walks, and thefoot of the user is prevented from being flattened by allowing the tibiaof the user to support a weight of the user when the user stands.

A plurality of impact absorbing caps having different impact absorbingdegrees are provided, and one of the impact absorbing caps isselectively coupled with the heel according to a weight of a user.

In addition, the human body-balancing footwear further includes animpact absorbing unit provided at an upper portion of the sole part. Theimpact absorbing unit includes first cushion patterns prepared in arectangular shape (“□”) and arranged on a surface of a heel section,first support ribs prepared in a cross shape (“+”) and installed at aboundary part between the first cushion patterns, second cushionpatterns prepared in the rectangular shape (“□”) and arranged on asurface of a sole section, second support ribs prepared in the crossshape (“+”) and installed at a boundary part between the second cushionpatterns, cushion balls installed at an intersection between the firstcushion pattern and the first support rib which makes contact with aheel of a user foot, a plurality of air holes formed on a bottom surfacebetween the first cushion part and the first support rib, a distributionpassage provided in a transverse direction at a boundary part with thesole section by making a wall at an outer peripheral surface of the heelsection, a supply passage wall installed at a boundary part between thedistribution passage and the sole section and having a plurality ofsupply passages, and an air passage formed in the sole section andconnected to the supply passage wall.

In addition, the weight shift can naturally occur outside the frontportion of the heel part of the footwear. The linking member is providedto align the heel part in line with the front portion of the sole partso that the balance of a human body can be excellently maintainedthrough the function of the tibia (tarsal joint or fifth rough surfaceof the arch bone of the foot). Accordingly, when a wearer walks, thetibia maintains the balance of the human body so that the wearer canwalk safely. When the wearer stands, the tibia supports the weight ofthe wearer, so that the feet of the wearer can be prevented from beingflattened.

Advantageous Effects

As described above, a human-body balancing footwear providing a cushionsuitable for the weight of a user while preventing the user from beingknock-kneed or bandy-legged according to the present invention has thefollowing effects.

First, a person can the most naturally walk as if the person walks inbare feet due to the heel part of the footwear having the shape similarto that of the heel of a human body. The heel part, which protrudes at aright angle according to the related art, is rounded similarly to theshape of the heel of the human body, so that the external impact can beprimarily reduced. In addition, the elasticity of the impact absorbingcap secondarily absorbs the impact when the heel part makes contact withthe ground. Accordingly, the soles and the ankles of person feet areprotected, and the fatigue caused by accumulated impacts can be reduced,so that the user has a comfortable daily life.

Second, the impact absorbing cap is divided into left and rightsections, so that the impact absorbing cap can be frequently replacedwith new one. Accordingly, when one of the left or the right sections isworn early due the bad walking posture of a user, the worn section canbe immediately replaced with new one, so that the balance can bemaintained in the left and right sections. Accordingly, the legs of anadolescent under the growth period can be preliminarily prevented frombeing knock-kneed or bandy-legged as the ankle joint of the adolescent,which is twisted due to the deformed heel part of the footwear, exerts abad influence on the legs of the adolescent. In addition, the human-bodybalancing footwear according to the present invention can preventproblems resulting from the deformation in the backbone of theadolescent, so that the balance of the human body can be veryeffectively maintained.

Third, since the human-body balancing footwear according to the presentinvention is equipped with a weight-adjustable cushion, persons havingdifferent weights can select and use a cushion allowing he/she to feelthe most comfortable. Accordingly, the soles or the joints of thepersons can be very effectively protected.

Fourth, since the sole part of the human-body balancing footwearaccording to the present invention has a shape similar to that of thesole of a human being which is the most comfortably developed throughthe evolutionary process, the human-body balancing footwear according tothe present invention is an ergonomic footwear allowing a person to feelthe most comfortable as if the person walks in bare feet on the cushionyplace.

Fifth, only when a heel part of typical dress shoes, a portion of whichis worn early, is frequently replaced with new one, the ankle joint of aperson may be prevented from being deformed. In the case of theconventional footwear, the heel part cannot be replaced with new one ormust be replaced with new one in a heel bar by paying too much money, sothat time and money may be wasted. In contrast, the footwear equippedwith the impact absorbing cap according to the present invention can besimply replaced with new one at home or in an office, so that time andmoney may not be wasted.

Therefore, since the human-body balancing footwear capable of preventingknock-knee and bandy-leg according to the present invention is the mostergonomically made, the human-body balancing footwear can provide a userwith a comfortable feeling that has never been provided in a footwearaccording to the related art. In particular, since the backbone of aperson as well as the sole and the joint of the person can be protected,the human-body balancing footwear has the value in the use for adults aswell as adolescents under the growth period.

BEST MODE Mode for Invention

The present invention will be described in detail with reference toaccompanying drawings.

As shown in FIGS. 1 to 3, a human-body balancing footwear 100 accordingto the present invention includes an upper leather 110 covering a footof a user, and a shoe liner part (not shown), an insole part 120, and asole part 130, which are sequentially stacked downwardly from the upperleather 110, and may further include a heel part 140 provided at a rearportion of the sole part 130 and an impact absorbing cap 150 coupledwith the heel part 140.

The impact absorbing cap 150 provides a cushion function for the heelpart 140 to absorb an impact applied to the heel part 140 and isreplaceable if necessary. Preferably, the impact absorbing cap 150includes a material representing elasticity greater than that of theheel part 140.

Referring to FIG. 4, the impact absorbing cap 150 may include a firstcap 151 and a second cap 152. The first cap 151 may be coupled with anouter side portion 141 of the heel part 140 corresponding to the outsideof the foot of a user, and the second cap 152 may be coupled with aninner side portion 142 of the heel part 140 corresponding to the insideof the foot of the user.

The impact absorbing cap 150 may be detachably coupled with the heelpart 140. To this end, the first cap 151 of the impact absorbing cap 150includes first and second coupling protrusions 151 a and 151 b, and theouter side portion 141 of the heel part 140 may include first and secondcoupling grooves 141 a and 141 b into which the first and secondcoupling protrusions 151 a and 151 b are fitted, respectively.

Preferably, the first coupling groove 141 a is formed in a frontsidewall of the heel part 140, and the second coupling groove 141 b isformed in a rear sidewall of the heel part 140. The first and secondcoupling protrusions 151 a and 151 b may preferably have curved frontends to improve the coupling strength.

In addition, the second cap 152 of the impact absorbing cap 150 includesthird and fourth coupling protrusions 152 a and 152 b, and the innerside portion 142 of the heel part 140 may include third and fourthcoupling grooves 142 a and 142 b into which the third and fourthcoupling protrusions 152 a and 152 b of the second cap 152 are fitted.

Preferably, the third coupling groove 142 a is formed in the frontsidewall of the heel part 140, and the fourth coupling groove 142 b isformed in the rear sidewall of the heel part 140. The third and fourthcoupling protrusions 152 a and 152 b preferably have curved front endsto improve the coupling strength.

According to another embodiment, the impact absorbing cap 150 may havecoupling grooves, and the heel part 140 may have coupling protrusions.

As shown in FIG. 5, according to the embodiment, the first cap 151includes a fitting protrusion 151 c extending along the edges thereof,and the outer side portion 141 of the heel part 140 is provided thereinwith a fitting groove 141 c extending along the sidewall of the heelpart 140, in more detail, the sidewall of the outer side portion 141, sothat the fitting protrusion 151 c may be fitted into the fitting groove141 c. Accordingly, the first cap 151 is mounted on the entire portionof the heel part 140 and coupled with the heel part 140. Since thesecond cap 152 has the same shape as that of the first cap 151, thedetail thereof will be omitted.

Since the impact absorbing cap 150 is detachably coupled with the heelpart 140, the impact absorbing degree of the impact absorbing cap 150can be adjusted according to the weights of users.

In other words, a plurality of impact absorbing caps 150 having variousimpact absorbing degrees are manufactured so that impact can be the mostperfectly absorbed according to the weight of a user, and the impactabsorbing cap 150 selected according to the weight of the user is nestedon the heel part 140, thereby allowing the user to feel comfortable incushioning regardless of the weight of the user.

In this case, since the impact absorbing cap 150 is divided into thefirst and second caps 151 and 152, at least one of the first and secondcaps 151 and 152 can be selectively replaced with new one.

Referring to FIGS. 6 and 7, the first cap 151 of the impact absorbingcap 150 according to the present invention includes a first cushion part151 d coupled with the bottom surface of the heel part 140, a secondcushion part 151 e coupled with the rear surface of the heel part 140,and a third cushion part 151 f linking the first cushion part 151 d withthe second cushion part 151 e in the form of a round, therebysurrounding the bottom surface and the rear surface of the heel part140. In this case, since the second cap 152 of the impact absorbing cap150 may have a shape corresponding to the shape of the first cap 151,the details of the second cap 152 will be omitted.

The human-body balancing footwear 100 according to the present inventionmay further include a linking member 160. The linking member 160 linksthe heel part 140 with the front portion of the sole part 130 along theedge of the heel part 140 corresponding to the outer portion of the footof the user. Accordingly, when a wearer walks, the linking member 160allows the tibia of the wearer to maintain the balance of the body sothat the wearer can walk safely. In addition, the linking member 160allows the tibia of the wearer to support the weight of the user,thereby preventing the foot of the wearer from being flattened.

In this case, preferably, the linking member 160 is spaced apart fromthe heel part 140 by a predetermined distance. Accordingly, the spacesufficient to couple the first coupling protrusion 151 a with the firstcoupling groove 141 a is ensured.

Meanwhile, the human-body balancing footwear 100 according to thepresent invention may further include an impact absorbing unit 200provided on the sole part 130. The impact absorbing unit 200 may be usedas the insole part 120 or the shoe liner part.

Referring to FIGS. 8 to 10, the impact absorbing unit 200 according tothe present invention includes a heel section 210 and a sole section220, and includes a supply passage wall 222 equipped with a supplypassage 223, which is installed at the boundary part between the heelsection 210 and the sole section 220. The impact absorbing unit 220 ismolded by using a material such as silicon, rubber, and urethane.

The heel section 210 has a shape of the heel of the foot. As shown inFIG. 11, the heel section 210 is provided on the surface thereof with afirst cushion pattern 212 prepared in a rectangular shape (“□”). A firstsupport rib 213 having the cross shape (“+”) is installed at everyboundary part between first cushion patterns 212. A cushion ball 214 isinstalled at every intersection between the first cushion pattern 212and the support rib 213.

A plurality of air holes 211 are formed in the bottom surface betweenthe first cushion pattern 212 and the first support ribs 213.

The cushion ball 214, the first cushion pattern 212, and the firstsupport rib 213 have a narrow upper portion and a wide lower portion.The cushion ball 214, the first cushion pattern 212, and the firstsupport rib 213 have the height of about 7 mm, the height of about 6 mm,and the height of about 5 mm, respectively.

Accordingly, the heel section 210 making contact with the heel of thefoot of the user has a multi-stage cushion function by the first cushionpattern 212, the first support ribs 213, and the cushion balls 214.

In addition, the heel section 210 is provided at an outer peripheralsurface thereof with a wall and has a distribution passage 215 providedin a transverse direction at the boundary with the sole section 220.

The sole section 220 has the shape of the foot excluding the heel of thefoot. As shown in FIG. 12, the sole section 220 is provided on thesurface thereof with second cushion patterns 224 prepared in arectangular shape (“□”). A second support rib 225 prepared in a crossshape (“+”) is installed at every boundary part between second cushionpatterns 224. Accordingly, the second support rib 225 has differentheights in transverse and longitudinal directions. The sole section 220has at least three air passages 221 extending with a long length towardthe front of the foot.

In addition, as shown in FIG. 10, a supply passage wall 222 is installedwith a supply passage 223 at the boundary parts between the distributionpassage 214 and the sole section 220.

A plurality of lines are formed on the upper surface (shoe liner part orthe contact surface with the sole of the user) of the impact absorbingunit 200 so that the impact absorbing unit 200 can be cut and usedaccording to the foot size of the user. In addition, the surface of theimpact absorbing unit 200 is treated as a rough surface, so that thefoot of the user can be prevented from being slipped in the human-bodybalancing footwear 100.

The impact absorbing unit 200 having the above structure according tothe present invention can be manufactured through the injection-molding.The first cushion pattern 212 and the first support rib 213 arealternately mounted on the surface of the heel section 210, and thesecond cushion pattern 224 and the second support rib 225 arealternately mounted on the surface of the sole section 220. In addition,in the sole section 220, the second support rib 225 has differentheights in the transverse and longitudinal directions, and the secondcushion pattern 224 is formed higher than the second support rib 225. Inaddition, the cushion balls 214 are mounted on the first cushion pattern212 and the first support rib 213 of the heel section 210, so that thecushion balls 214 are formed higher than the first cushion pattern 212,and the first support rib 213 is formed lower than the first cushionpattern 212.

The first and second cushion patterns 212 and 224, the first and secondsupport ribs 213 and 225, and the cushion balls 214 have narrow upperportions and wide lower portions, and the height of the multi-stagecushion is reduced toward the sole section 220 from the heel section210, so that a gentle slope is formed. Accordingly, air is introducedthrough the air holes 211 when the heel of the foot of the user islifted, and the air holes 211 are closed by the weight of the user whenthe heel of the foot makes contact with the ground, so that theintroduced air is supplied toward the front of the human-body balancingfootwear 100. In this case, the air is supplied between toes of the userthrough the air holes 211, the heel section 210, the distributionpassage 215, the supply passage 213 of the supply passage wall 222, andan air passage 221 of the sole section 220.

Accordingly, wind forcibly blows inside the human-body balancingfootwear 100, and the internal air of the human-body balancing footwear100 is exchanged. Simultaneously, the multi-stage cushion functioncaused by different internal heights of the human-body balancingfootwear 100 is performed. In the impact absorbing unit 200 according tothe present invention, since the warm air around the sole of the foot ofthe user is discharged out of the human-body balancing footwear 100 bypushing the warm air to the top of the foot, the internal temperature ofthe human-body balancing footwear 100 can be maintained at a uniformlower temperature and a user can feel fresher at the sole of the foot.In addition, a great amount of moisture is exhausted to the outsidetogether with the warm air, thereby preventing fungus, eczema, and thelike. In addition, foot odor can be significantly reduced, and benefitscan be provided to a diabetic, a salesman walking for a long time, andother persons having serious foot odor through the discharge of a greatamount of sweat.

In addition, the multi-stage cushion function is performed by the firstcushion pattern 212, the first support rib 213, and the cushion ball 214of the heel section 210. Due to the multi-stage cushion function, thefoot of the user is kept comfortably as if the user walks on the softgrass, so that the fatigue caused by the impact can be reduced, and thedead skin cell of the heel can be reduced due to the effect ofcomfortable acupressure-type massage.

A plurality of impact absorbing units 200 according to the presentinvention can be provided with different strengths, so that impact canbe the most perfectly absorbed according to the weights of the user. Theimpact absorbing units 200 are selectively mounted on the human-bodybalancing footwear 100 according to the weight of a user, so that a usercan feel comfortable in cushioning regardless of the weight of the user.

Hereinafter, the function and the operation of the human-body balancingfootwear 100 according to the present invention will be described.

The first and second coupling protrusions 151 a and 151 b of the firstcap 151 of the impact absorbing cap 150 are fitted into the first andsecond coupling grooves 141 a and 141 b of the outer side portion 141 ofthe heel part 140, and the third and fourth coupling protrusions 152 aand 152 b of the second cap 152 are fitted into the third and fourthcoupling grooves 142 a and 142 b of the inner side portion 142 of theheel part 140. Accordingly, the impact absorbing cap 150 can be easilycoupled with the heel part 140 without an additional adhesive. Inaddition, even if one of the first and second caps 151 and 152 is wornearly, only the worn cap can be replaced with new one.

In addition, the outside of the heel part 140 is aligned in line with afront portion of the sole part 130 through the linking member 160interposed between the heel part 140 and the front portion of the solepart 130, so that the weight of the user can be continuously shifted andthe function of the tibia can be activated.

When the user walks, the ankle of one leg is directed forwardly in thestate that the ankle of the leg is slightly spread, and the leg directedforwardly makes contact with the ground. In this case, the end portionof the heel protruding at a right angle applies useless impact to theuser. Accordingly, the useless impact can be reduced by rounding theheel to the rounding extent of the heel of the user foot.

After one foot makes contact with the ground, the whole body of the useris inclined forwardly, so that the weight shift of the user occurs, andan ankle joint forms an acute angle beyond a right angle so that theground is pushed by the front portion of the foot to form thepropulsion. This procedure is alternately repeated by left and rightlegs, thereby forming a walking step. Recently, most footwears have theheel and the sole completely separated from each other to make a stepdifference, so that the weight shift of the user does not continuouslyoccur. Accordingly, a user may walk with difficulty, or the whole bottomsurface of the footwear is flattened, so that the foot of the user maybecome a cavus-footed state, or a flat footed.

However, in the human-body balancing footwear 100 according to thepresent invention, impact is primarily reduced by rounding the heel part140 similarly to the foot heel of the user, secondarily reduced by theelasticity of the impact absorbing cap 150 which is divided in left andright sections to cover the heel part 140, and tertiarily reduced by theimpact absorbing unit 200 acting as the insole part 120 or the shoeliner part. Therefore, the impact is almost perfectly absorbed, so thatthe sole and the ankle of the user can be protected. In particular,since the impact absorbing cap 150 divided into left and right sectionsis covered on the heel part 140, one of the left and right sections,which is worn early, can be simply replaced with new one, so that thebalance of the footwear can be maintained. Accordingly, the human-bodybalancing footwear 100 according to the present invention can preventthe deformation in the ankle joint caused by the difference in wear ofthe heel part 140. The legs of adolescents under growth periods can beprevented from being knock-kneed or bandy-legged as the deformation inthe ankle joint influences the leg joint. The human-body balancingfootwear 100 according to the present invention allows the adults touniformly maintain the balance of the body, so that the footwear is ofbenefit to the health. Further, the human-body balancing footwear 100according to the present invention provides cushion suitable for theweight of the user, so that the user can feel comfortable as if the userwalks on the grass.
